Problems solved by technology

The organic glass transparent parts used here are extremely sensitive to the application part, so the requirements on the glass surface are extremely strict (scratch depth on the glass surface is less than 0.01mm, which can be repaired later, and if it is deeper than this, it will be treated as waste), so this type of organic glass extremely expensive
[0003] Most of the transparent parts of plexiglass are PMMA (acrylic) or polycarbonate materials. The material itself is not very hard and is easily polluted by chemicals, so it is extremely difficult to protect
[0004] One of the existing protection measures in the industry is to use film and paper materials to cover, and the edges are fixed to the body with tape. Ho

Abstract

The invention provides an aircraft organic glass surface protecting film and a preparation method thereof. The protecting film comprises components such as ethylene-vinyl alcohol copolymer, butyl acrylate resin, polyurethane, graphene, composite emulsion and organosiloxane. The components are mixed uniformly, is subjected to three-section type heating, is extruded out of a film blowing machine through a single screw, and is extruded and cooled to obtain the aircraft organic glass surface protecting film. The protecting film does not have chemical corrosion, residue or requirements for aging, meanwhile, the thickness of the protecting film is adjustable, and the protecting film is scratch-resistant, resists external force impact and has high chemical resistance.

Description

technical field [0001] The invention relates to an aircraft plexiglass surface protective film and a preparation method thereof. Background technique [0002] Due to the weight, thickness, mechanics or other technical requirements of domestic and foreign aircraft, motor vehicles, ships and other means of transport, a large number of plexiglass transparent parts are used for perspective and observation applications in the front shield, side shield and porthole of the means of transport. The organic glass transparent parts used here are extremely sensitive to the application part, so the requirements on the glass surface are extremely strict (scratch depth on the glass surface is less than 0.01mm, which can be repaired later, and if it is deeper than this, it will be treated as waste), so this type of organic glass The cost is extremely high. [0003] Most of the transparent parts of plexiglass are PMMA (acrylic) or polycarbonate materials. The material itself is not very har...
